Cystocerebral Syndrome in a Patient with Altered Mental Status.

BACKGROUND Cystocerebral syndrome is delirium occurring in the elderly that results from urinary retention and acute bladder distension. Urinary retention can cause cerebral issues, such as altered mental status, without having an infection present. The pathophysiology is possibly due to increased catecholamine secretion while attempting to micturate. Due to its presenting symptoms, most physicians begin cerebrovascular workup, performing unnecessary and, often, invasive imaging studies. Although easily overlooked as a differential diagnosis, cystocerebral syndrome is an easily treatable cause of delirium and should be considered during treatment of elderly patients with delirium. CASE REPORT The patient was an 89-year-old man with a medical history of chronic obstructive airway disease, dementia, hypertensive disorder, and gastroesophageal reflux disease who presented with altered mental status secondary to urinary incontinence. The computed tomography scan without contrast showed a large volume of impacted stool in the cecum, with a distended urinary bladder. This case report describes his presentation, medical treatment, and outcome and discusses areas of gap improvement. CONCLUSIONS To date, there are only a handful of published articles on cystocerebral syndrome. This case report aims to add the awareness of bladder distention as an etiology of cystocerebral syndrome to the body of knowledge in the scientific community in the hope that patients will be identified and treated earlier, more safely, and at a reduced cost. Cystocerebral syndrome needs to be extensively addressed in research, and physicians should consider it one of the important differential diagnoses of delirium among elderly men.

Increased anxiety and emotional lability in a patient with SDHB gene mutation paraganglioma: a call to multidisciplinary approach.

Paragangliomas are neuroendocrine tumors that have the potential to secrete catecholamines. They have been linked to genetic mutations in the mitochondrial succinate dehydrogenase (SDH) complex. Patients can experience both physical symptoms and psychiatric symptoms like anxiety, depression, and psychosis. These symptoms can occur as paroxysmal episodes with periods of increased catecholamine secretion. We describe a patient with SDHB gene mutation, who has been diagnosed with a jugular paraganglioma, and was brought to the hospital under Baker Act for threats made online. Since diagnosis this patient has been experiencing both anxiety and post-traumatic stress disorder (PTSD). The patient and a family member report increased emotional lability, and the patient reports multiple daily episodes of anxiousness. This case outlines the connection between paragangliomas and psychiatric symptoms, the impact they can have on patients' daily lives, and the importance of addressing the possibility of these symptoms and establishing a multispecialty healthcare team at the time of diagnosis.

Providencia alcalifaciens in a patient with a staghorn calculus: a novel presentation.

A member of the Enterobacteriaceae family, Providencia alcalifaciens is typically recognized as a source of gastrointestinal illness. Although its pathogenicity is not well known, many studies have suggested its mechanism of action involves the invasion of the intestinal mucosal layer. Although P. alcalifaciens is a urease producing microorganism, it has not been associated with the formation of a staghorn calculus in the setting of a urinary tract infection. This organism is neither commonly pursued in research or investigation nor is it commonly tested for in the clinical setting. This is especially true when combined with other disease processes, such as calculus formation. The advancement of antibiotic resistance, such as carbapenemase-producing strains, should bring more attention and routine investigation to this organism in the acute stage of infection. In this case report we introduce a 43-year-old Cuban female, who presents with a left-sided staghorn calculi and urine culture positive for carbapenemase-producing P. alcalifaciens.
